Hi Viv,
Not knowing what you have searched, I have just checked out my Kirk Braddan Parish Burial Register book four 1849 - 1981 surnames D to L and I noticed five and a half A4 pages of Kewleys, many of the names you quoted are there . Also remember there is a famous Book 2 of K.Braddan Burials being re - indexed and this is held in the Manx Museum. I have quoted this many times here, and I even found one of my ancestors via a local researcher ,due could not get home at the time.
My advice is contact the Manx Museum and check out this elusive BOOK 2 of Kirk Braddan Burials. They also supply names of local researchers.

" Happy searching" and never give up.
